Ice body maker collecting bin control

ABSTRACT

An ice body maker having a mold in which ice bodies are formed with means for ejecting the ice bodies to a collecting bin along a preselected path. A control is provided including a holding means which interrupts the movement of the ice bodies along the ejection path to hold them in spaced relationship to the collecting space, permitting them to dry. During this drying period a sensing portion of the control moves through the collecting space to sense the level of ice bodies therein for automatically maintaining a preset level. During movement of the sensing portion of the control through the collecting space, the holding means prevents the ice bodies being ejected from the mold from falling onto the sensing portion, thereby preventing them from being raked from the bin defining the collecting space by the sensing portion should the bin be removed from the ice body maker. The control is adjustable to permit different preset levels of ice bodies in the collecting space to be obtained as desired. The adjustment of the control may be maintained by means of a retaining member.

ICE BODY MAKER COLLECTING BIN CONTROL BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to ice body makers and in particular to controls for automatically controlling the operation thereof to maintain a preselected level of predryed ice bodies in a collecting bin associated therewith. The control further prevents accidental ejection of ice bodies from the bin upon subsequent removal thereof from the ice body maker.

2. Description of the Prior Art In one form of improved ice body maker disclosed in Linstromberg U.S. Pat. No. 3,280,578, owned by the assignee of the instant invention, a mold is provided with an ejecting means for transferring the formed bodies to a subjacent col lecting bin. In Heath U.S. Pat. No. 2,778,198, also owned by the assignee hereof, an ice-making machine is disclosed having a modified form of level-sensing means wherein intercepting members are operated by the control concurrently operating the sensing arm to hold the relatively wet ice bodies for a period of time before delivery thereof to the subjacent collecting bin.

SUMMARY OF THE INVENTION The present invention comprehends an improved means for controlling the transfer of ice bodies in an ice body maker. In the structure disclosed herein, an elongate control element is provided having different portions providing a number of different coordinated functions whereby an improved control of the ice body transfer is obtained. Thus, in the present invention, the elongate control element includes a first portion selectively interrupting the transfer of the ice bodies from the mold to the collecting space whereby the ice bodies may be held to permit refreezing thereof after removal from the mold so that they will be substantially completely dry when they are delivered to the collecting space.

The control element further includes a sweep portion spaced from the holding portion by a connecting portion. The holding portion retains the ice bodies during. the time the sweep portion moves through the collecting space to sense the level of ice bodies therein and thus prevents pileup of the ice bodies on the sweep portion during the sensing cycle. As a result of the improved holding function, the transferred ice bodies are prevented from being raked from the collecting space by the sweep portion should the bin, defining said collecting space, be subsequently removed from association with the ice body maker.

The present invention further comprehends providing such a control element with means for permitting selective adjustment so as to maintain different preselected levels of ice bodies in the collecting space, as desired by the user. The adjusting means is manually operable to permit facilitated adjustment and readjustment as desired. One highly desirable advantage of this feature is the adaptability of the control for use with different-size collecting bins. Such adjustability is also advantageous where the ice body maker is installed by the user in the field.

The improved control is extremely simple and economical of construction, while yet providing the desirable features discussed above.

More specifically, the invention comprehends an improved means for controlling the transfer of ice bodies in an ice body maker having a mold in which ice bodies are formed, means defining a collecting space subjacent the mold, and means for transferring the formed ice bodies along a preselected path from the mold to the collecting space. The transfer-controlling means is defined by an elongate control element having a holding portion, a sweep portion, and a connecting portion connecting the sweep portion to the holding portion. Operating means is provided for selectively disposing the holding portion in a first position blocking said preselected path for interrupting the transfer of the ice bodies, thereby maintaining the ice bodies spaced from the collecting space for a predetermined time period, and concurrently moving the sweep portion through the collecting space to sense the level of ice bodies already, present in the collecting space. After the predetermined time, the operating means moves the holding portion from the first position to permit completion of the transfer of the ice bodies to the collecting space and disposes the sweep portion out of the path followed by the ice bodies during their transfer to the collecting bin.

Further, more specifically, the invention comprehends the provision of a deformable connecting portion permitting adjustment of the disposition of the sweep portion relative to the holding portion. The invention also comprehends provision of a retaining member for holding the sweep portion in the adjusted position relative to the holding portion whereby the sweep portion may be adjusted to sense any one of a plurality of different levels of collected ice bodies in the collecting space.

DESCRIPTION OF THE PREFERRED EMBODIMENT In the exemplary embodiment of the invention as disclosed in the drawing, an ice body maker generally designated is shown to be installed in a refrigeration apparatus 11 of conventional construction. Apparatus 11 may include a cabinet 12 defining a refrigerator space 13 and a freezer space 14. Controlled access to spaces 13 and 14 may be had by suitable doors 15 and 16 respectively. Refrigeration may be effected by suitable means, herein illustratively comprising a compressor 17, a condenser 18, a capillary 19 and conduits 20 and 21 for delivering refrigerant to and from an evaporator 22 pro vided within the cabinet 12. Freezer space 14 is maintained at a below freezing temperature whereby water delivered to the ice body maker 10 through a conventional water solenoid 23 may be frozen into ice bodies which are automatically harvested.

The icemaker 10 as shown in FIG. 2 includes a mold 29 in which the ice bodies 30 (FIG. 4) are formed and from which the ice bodies are ejected to a subjacent bin 25 defining a collecting space 26 (FIG. 1) by means of an ejector 31 which sweeps through the mold during the ejection cycle. The ejection member swings the ice bodies out of mold 29 and against a stripper member 32 which effectively positively strips the ice bodies from the ejector 31 and causes them to fall downwardly into the collecting bin 25. Cyclical operation of ejector 3] is automatically effected by a control generally indicated 27 disposed at the forward end of the mold 29. In addition to cycling the ejector 31, control 27 further automatically provides for refilling of the mold for subsequent further ice body formation therein, in the event that the level of ice bodies in the subjacent bin 25 is below a preselected full level. For a detailed description of the operation of control 27, reference may be had to the hereinbefore identified Linstromberg U.S. Pat. No. 3,280,578. Mold 29 defines a plurality of upwardly opening cavities 33 in which ice bodies are formed. The water from which the ice bodies are formed is delivered to mold 29 by means of an inlet 34 connected to solenoid-operated valve 23 (FIG. 1) through a suitable delivery tube. Valve 23 is connected to a suitable source of water under pressure (not shown).

Referring to FIGS. 2, 3, and I2; mold 29 herein more specifically comprises a tray structure having a bottom wall 35 and sidewalls 36 and 37. A calrod heating element 44 is pressed into bottom wall 35 to heat the mold during the ejection operation, thus aiding in said ejection operation. A plurality of partition walls 38 extend transversally across the mold to define with the above-indicated tray walls the cavities 33 in which ice bodies are formed. Herein each cavity 33 is partially divided by a partial dividing wall 39, which extends transversally across the cavity as best seen in FIG. 12. Each of the partition walls and dividing walls is provided with a recessed upper edge portion through which water flows from the end cavity successively forward to the respective cavities until all cavities are filled to a level L as shown in FIG. 3. Thus, the recessed edge portion of respective partition and dividing walls over which the water flows effectively form a plurality of weirs over which a small body or bridge of connecting ice forms during the freezing operation. As shown in FIG. 12, however, the recess 40 in the upper edge of the partial dividing wall 39 is substantially larger than the recess 41 in the partition wall 38. Thus, the connecting portion of ice which forms in the space defined by recess 40 is substantially larger than the connecting length of ice which forms in the recess defined by opening 41. Thus, a connecting ice portion 42 is fonned on ice body 30 the protective shown in FIG. 4. Connecting portion 42 is preferably sufficiently strong to prevent breaking of the ice body during the normal ejection and transfer thereof from mold cavity 33 to collecting bin 25. Illustratively, the connecting portions 43 formed in the opening 41 of the mold shown in FIG. 12 may break as a result of the impact of the ice bodies resulting from their free fall into collecting bin 25 the connecting portions 42 being sufficiently strong to preclude breakage as from such impact forces. Thus, the mold as shown in FIG. 12 produces bifurcated ice bodies as shown in FIG. 4.

In order to sense the level of ice bodies 30 as they accumulate in bin 25, this invention comprehends the provision of a novel sensing arm structure 28 actuated by control 27 for con trolling the automatic harvesting operation so as to maintain a preselected level of ice bodies in collecting space 26 as desired by the user. The control 27 operates the sensing arm 28 through a connecting portion 45, as best seen in FIGS. 3 and 11. The sensing arm 28 includes a holding portion 46, a sweep portion 47, and a connecting portion 48 which, as seen in FIG. 11, effectively define a generally U-shaped structure wherein the holding portion 46, and sweep portion 47 define the legs of the U-shaped structure and the connecting portion 48 defines the bight of the U-shaped structure.

As shown, holding portion 46 may be substantially rectilinear and extend adjacent the stripper 32 of the mold 29 onto which the ice bodies 30 are delivered during an intermediate stage of the ejection cycle. The sweep portion 47 is arcuate and the connection portion 48 is also arcuate. The arcuate configuration of connection portion 48 and sweep portion 47 effects an improvement over prior-art sensing arm structure as follows: Should the user of the icemaker remove bin 25 from the freezer compartment by sliding it in the direction indicated by arrow 56, edge 57 of bin 25 contacts an arcuate portion of sensing arm 28. This allows the arm to easily ride up over edge 57 and thus not catch thereon or rake ice bodies from bin 25.

The sensing arm may be formed of a suitable strong material such as a metal rod or wire, and in the illustrated embodiment is formed of stainless steel having a spring temper. Further, illustratively, the sweep portion 47 may have a relatively large arcuate radius varying from approximately 3% inches adjacent the connecting portion 35 to approximately 4% inches adjacent the distal end 49 thereof. The connecting portion 48 may have an arcuate radius of approximately 1% inches and may include an upturned arcuate potion 50 extending from the distal end 51 of the holding portion 46. As seen in FIG. 11, the sweep portion 47 extends downwardly into the collecting space 26 while the distal end 49 is juxtaposed to the holding portion 46 adjacent the connection 45.

As shown in FIG. 11, the distal portion 49 may be adjustably spaced from the holding portion 46 by means of a connector strap 52 which connects end 49 to holding portion 46. As shown in FIG. 10, the connector strap 52 may comprise a plastic element having a pair of apertures 53 and 54 at the opposite ends thereof. Aperture 53 is preferably slightly larger than the cross section of the sensing arm 28 to permit facilitated movement of the strap 52 onto the holding portion 46 from the distal end 49 thereof. The distal end 49 is inserted into the smaller aperture 54 whereby the spacing of end 49 from the holding portion 46 may be retained by the canted locking engagement of the strap 52 with the respective rod portions 46 and 49. A protective cap 55 may be installed on the end of the rod 28.

The operation of sensing arm 28 with the ice body maker 10 may best be understood by reference to FIGS. 5-9 of the drawings. Thus, as shown in FIG. 5, the ice-harvesting operation is initiated by counterclockwise rotation of the ejector 31 as seen herein, with the sensing arm 28 disposed in a lowermost level-sensing position within the bin space 26. As ejector 31 continues to rotate, the sensing arm 28 is swung outwardly from the collecting bin 25, as shown in FIG. 6. Continued rotation of ejector 31 causes it to forcibly engage the upper surface 56 of the ice bodies and urge the ice bodies outwardly from the mold cavities 33 in a pivotal movement, as shown in FIG. 7. At the same time, control 27 causes the sensing arm 28 to swing back downwardly into the collecting space 26. At the position of FIG. 7 wherein the ejector fingers have moved approximately 270 from the start position, the control 27 brings the sensing arm substantially fully to the lowermost sensing position.

As shown in FIG. 8, the continued rotation of ejector 31 now brings the ice bodies 30 outwardly from the mold cavities 33 whereupon the ice bodies are stripped from ejector 31 by plastic stripper 32. Movement of ice bodies 30 into the subjacent collecting space 26 is blocked by the holding portion 46, and ice bodies 30 .remain on top of stripper 32, as shown in FIGS. 8 and 11. Thus, the ice bodies are held on stripper 32 for a shot period of time while any melt formed thereon as a result of heating of the mold in the ejection cycle tends to refreeze whereby the ice bodies are dried before completion of their transfer from the mold to the collecting bin 25. Further, the holding portion 46 prevents the ice bodies from falling into the collecting space 26 prior to the movement outwardly of the sensing arm 28, as shown in FIG. 9, during the final portion of the harvesting operation. This effectively precludes the ice bodies 30 from piling up on sweep portion 47 during the ejection operation. Should such piling up be permitted, ice bodies 30 might be accidentally raked from bin 25 upon its removal from freezer compartment 14.

As shown in PK]. 9, the ejector 31 continues to rotate back to the starting position of FIG. 5 while the sensing arm 28 is again brought down into the collecting space 26 subsequent to the delivery of the ice bodies 30 thereinto to sense the new level of ice bodies in space 26. In the event that the level reaches the preselected level, the movement of the sweep portion 47 of the sensing arm 28 is arrested, thereby preventing further cycling of the ice body maker until such time as the level is lowered as by the removal of ice bodies from the collecting bin whereupon the arm may move to the lowermost position to initiate a subsequent ice body making and harvesting operation.

To adjust the ice body maker to provide any one of a plurality of different levels of ice bodies in the collecting bin 25, the user may merely bend the connecting portion 48 to raise or lower the sweep portion 47 as desired (assuming that adjusting strap 52 is not used). Thus, as illustrated in FIG. ll, the connecting portion 48 may be bent to enlarge the radius thereof and lower the sweep portion 47 to the dotted line position providing a lower level of ice bodies in the collecting bin Alternatively, the adjusting strap 52 may be employed, as shown in FIG. 11, to retain the sweep portion 47 in any one of a plurality of different positions to obtain the desired adjustment of the level. The strap 52 may be suitably adjusted by movement of the distal end 49 of sweep portion 47 further into or outwardly of the aperture 54 with the adjusted positioning of the sweep portion 47 being retained by the frictional engagement of the strap with the sensing arm portions 46 and 47 in the respective apertures. Thus, not only does the strap 52 provide a means for adjustably connecting the distal end 49 of the arm 28 to the holding portion 46 to vary the disposition of the lowermost portion of the sweep portion 47, but it also stabilizes the sensing arm structure by effectively causing the sweep portion 47 to be connected to the upper portion of the sensing arm at each of the opposite ends thereof.

Where the adjustment of the disposition of sweep portion 47 is effected simply by suitably bending the connecting portion 48, the material of which sensing arm 28 is formed is preferably controlably deformable to permit the adjusted disposition to be maintained against the forces acting on the sensing arm in the normal sensing operations while yet the bending of the connecting portion 48 may be manually effected for facilitated adjustment by a user, such as a housewife. Where the connector strap 52 is utilized, the sensing arm material may be somewhat less rigid.

Thus, ice body maker 10 provides an improved control of the transfer of the ice bodies from the mold to the collecting space in the automatic harvesting operation. The control includes means for interrupting the transfer of the ice bodies sufficiently to assure a drying thereof before delivery to the collecting space and provides improved means for permitting variation in the preselected level of ice bodies in the collecting space, as desired by the user. The improved sensing arm further assures that the ice bodies will not pile up thereon during the ejection operation resulting in their accidental expulsion from the collecting bin should it be removed from the freezing compartment. The sensing arm structure is simple and economical of construction, while yet providing the above-discussed desirable features.
